V`IMPROVElllIENI IN COMBINED BLUGE AND' GULTIVATGR.

TO ALL WHOM IT MAY GONCERN:`

Be it known that we, ANTON ROMANN and JOHN PETERKAVO Wilton, in the county of Muscatine, and State of Iowa, have invented anew and useful machine for ploughing and cultivating corn and other crops grown and cultivated in like manner', end also for harrowing, said machine being known, designated, and called the Ro-man Cultivator and Harrow; and we do hereby declare that -the following is a full, clear, andv exactlescripti'on of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification.

A, the tongue or pole, to which the team is attached. B, the clevis, to which'the whiHe-trees are attached. -v

C,'th'e beam connecting the forward running-gear with the cultivator proper. D, the ,large forward wheels.

E, the lever, with a nut o n the lower end fitting on the screw-bolt F, by turning which the beam C is raised and'v lowered. F, large lscrewbolt, running through the beam C and axle M. M, a erookedaxle, part wood und. part iron, on whiehthe wheels D run, and through which the screw-holt F passes. G G G, three cross-bars, inrthe lnstor hin'dmost two of'which the' shovel-ploughs K K are set. I-I l-I, handles by which the -maehine -isv held and guided. I I, screw-bolts by which the small-wheels L L aroheld and raised or lowered. J' J, levers,

with nut on the lower end fitting on the screw-bolts I' I, and by turning which the small wheels L are regulated. K K, small shovel-ploughs, fastened in the cross-beams G by screws, nuts, and' braces, in such a manner as to be readily taken'out and replaced, In cultivating corn the two outside ploughsand-the Centre plough in the rear cross-bar G can be taken out; so as to allowthe lmachine to pass *directly over lone row of corn. L L, l

small wheels, bearing a great part of the weight of the machine, and by raising or 'lowering which the depth of' cultivation is regulated. I

When the shovels rest on the surface of the ground, the beam C and the bars are two feet from the ground. If it is desired to cultivate the soil deep, lowerY the beam C, by means of the screw F, and raise the small wheel L, by means of the screw I. If shallowcultivation is required, reverse this process. By proper adjnstmcnt.of.the screws the machine can be run on the wheels entirely, a convenience in vgoing to oir from the field. The rear bar G is seven feet long, and holdsrsev-en shovels K. The middle bar holds six shovels K.

When used-as a harrow, all the shovels should be'in. When used to cultivate corn .orotherA like erop, the

centre shovel in the rearbar should be removed, and the beam G and centre of the machine will pass directly over a row of corn, thus cultivatingiand ploughing the two spaces, each side of such row, at the same time. a I

What we claimen our invention, and desire to secure by Letters Patent, is- I 'lhe form and construction of the cultivatonand hai-row combined, when arranged, adjusted, and operated with lhe bolt F, beam C, and .axle M, as attached to the frame or bars G, vwith the regulating wheels L, as herein described and for the purposes set forth.
